高压氧对血管性痴呆大鼠海马胆碱能神经元的影响及行为学疗效

目的 研究高压氧(HBO)治疗对血管性痴呆大鼠海马胆碱能神经元及行为的影响。方法 制作血管性痴呆大鼠模型，随机分成对照组及治疗组，HBO治疗30d后，用Morris水迷宫检测大鼠空间记忆能力，免疫组织化学染色检测海马CA1区胆碱能神经元数目的变化。结果 治疗组大鼠空间记忆能力明显提高，海马CA1区胆碱能数目较对照组明显增加。结论 高压氧对血管性痴呆大鼠有明显治疗作用。

Effect of hyperbaric oxygen therapy on the cholinergic neurons of hippocampus and praxiology of vascular dementia rats

ObjectiveTo study the effect of hyperbaric oxygen therapy on the cholinergic neurons of hippocampus and praxiology of vascular dementia rats.MethodsThe vascular dementia models were made and divided into control and therapy group. After 30 days of HBO therapy, abilities of learning and memory of rats were tested by using the Morris water maze. Immunochemistry staining was used to observe the number of cholinergic neurons of CA1 subfield of hippocampus. ResultsAbilities of learning and memory of rats and the number of the neurons positive to ChAT like immunoreaction in the CA1 subfield of the hippocampus significantly increased in therapy group.ConclusionHyperbaric oxygen therapy is effective on the vascular dementia model rats.
